Greek Islands

The Greek Islands are the island groups of Greece located in the Aegean and Ionian Seas, forming one of the most extensive island archipelagos in Europe. A key fact is that Greece has roughly 6,000 islands and islets with about 227 inhabited.

Island types and experiences vary widely across the archipelago. Popular Cycladic islands such as Santorini and Mykonos are known for their cliffside towns and nightlife, while Crete is Greece’s largest island with mountain ranges, archaeological sites and long coastlines. The Ionian Islands offer a greener, more forested landscape and different architecture, and smaller groups such as the Saronic Islands are often visited on day trips from Athens.

The islands have been inhabited and connected to continental Greece since antiquity and show layers of Classical Greek, Byzantine, Venetian and Ottoman influence in architecture and archaeology. Over the 19th and 20th centuries they were integrated into the modern Greek state and developed as major tourist destinations.

Geographically the islands lie across the Aegean and Ionian Seas; the closest major city is Athens, which serves as the primary transport hub. Distances to Athens vary by group - many Cycladic and Saronic islands lie within a few tens to a few hundred kilometres of the city.

• Scale: Around 6,000 islands and islets belong to Greece, of which about 227 are inhabited, spread across the Aegean and Ionian Seas.
• Best time to visit: Peak visitor season runs from May to September when ferry and flight connections are most frequent and many facilities operate daily.
• Transport: A network of regular ferries and high-speed boats links the islands to Athens and to each other; travel times vary from under an hour to many hours depending on distance and vessel type.
